To all whom it may concern.-

Be it known that we, J OHN SHAW AINLEY and EDWIN SYKEs, subjects of King Edward VII of Great Britain, residing at udders field, in the county of York, England, have invented certain new and useful Improvements in Winding-Machines for Yarn or Thread, of which the following description, in'connection with the accompanying drawings, is a specification.

This invention has reference to machines for Winding yarn or thread upon paper, wood, or like tubes or spools, carried in bearings in pivotedframes and resting upon and being rotated by frictional contact with driven winding drums to wind the yarn thereon, the yarn being guided to the tube or spool through a cam slot or opening in the drum and thereby traversed from end to end of the cheese, cop or spool and cross wound thereon, our inventionrelating more particularly to those winding machines adapted for winding the yarn in cheeses or rolls for warping purposes, or on spools or cops for use as weft, means being provided for building 11 the yarn in gradually shortening chases or layers until a given diameter is attained and then building the yarn uniformly to the full diameter of the cheese or roll required for warp, any length of yarn remaining above what may be used as warp serving as weft, and if weft alone is required, the

winding is stopped when the shortest chase is laid on, the co thus formed being of ,a size and shape suite for. insertion in the shuttle.

In guiding and delivering yarn through a 7 split drum to the cheese, spool or bobbin, the

action of the sides of the cam slot or slit in the drum on the yarn in traversin it to and of the slot and have the reverse efiect upon objectionable action of the split drum on the fro is to twist it when engaged wit one side faces being very objectionable and injurious to the yarn. The object of our invention is to avoid the i yarn by employing means independent of the drum but actuated therefrom to guide the yarn to and traverse it upon the bobbin or spool, the split drum forming a cam for givmg the necessar traverse motion. We also provide linings or the sides or edges of the I,

cam groove or slit to form noiseless surfaces against which the means for guiding the yarn are adapted to engage and give a smooth silent motion.

We have shown our improvements as a plied to a machine provided with a variab e traverse motion for each bobbin or spool for building up the yarn so that it may beused either for warp or weft.

The novel features of our invention will be fully described in the subjoined specification and particularly pointed out in the following claims Referring to the drawings:'Figure 1 is transverse section of so much of a drum winding machine with individual varying traverse motions, as is essential to show the embodiment of our improvements; Fig. 2 is front elevation of a portion of the machine, looking in the direction of arrow 1 Fig. 1; Fig. 3 is plan view, on an enlarged scale, of a winding drum and means for giving a vg'rying traverse to the bobbin or spool holder, showing ourimproved means for guiding the yarn to the tube or bobbin. Fig. 4 is seetional elevation taken on line 2,- 3, Fig. 3. Fig. 5 is an enlarged elevation of the thread guiding device, detached, the portion of the winding drum shown beingin section; Fig. 6 is end elevation, partly in section, looking in the direction of arrow 4 Fig. 5, a portion of the drum being in section; Fig." 7 is plan view of Fig. 5, the winding drum being omitted; Fig. 8 is enlarged front elevation of parts, detached, for giving the variable traverse to the s 001 holder and for maintaining the spool ho der stationary when the cop or s' 001 attains apredetermined diameter, and

ig. 9 is elevation of a spool or cheese built up by the traverse motion shown on the drawlngs; Fig. 10 is a modification hereafter referred to.

In the drawings, a is the ordinary split winding drum for cross winding am or thread upon tubes or spools. b is t e main driving shaft having fast thereon the pulle s b from which rotary motion is imparted y ranged at eac side of the machine. I

In bearings in the brackets or pedestals 0 located at each side of the respective winding drums, is j ournaled the spindle or shaft (1 upon which is mounted, between each-pair of brackets c, the bobbin or spool holder e 115 ing bearings at its free ends torecelve and support the ends of'the short splndle'f on which the wooden orpaper tube or bobbin g .to receive the yarn, is first placed.

cords b and ulleys b to winding drums ar- IIC The tube g rests upon the periphery of the drum or and is driven by frictional contact therewith to wind on the yarn whose increasing diameter gradually moves the frame or holder e upon its fulcrum d from the position substantially as shown in full line in Fig 4, toward the position indicated by strong broken line in same figure.

The friction bowl or roll 6 at the rear end of the frame or holder e extends into the yoke or recessed end it of the arm or lever h pivoted at h on a stud or pin carried by the bracket i't secured to the framing of the mamaximum amount of traverse at chine and having an open ended slot at its lower end into which enters and engages the pin or stud 'i projecting from the boss or collar i secured on the traverse rod or shaft 7' extending longitudinally the full length of the machine. The rod 1 is attached at one end to the upper end of the lever j, see Fig. 2, pivoted at 7' to a bracket secured to the respective end frame of the machine. The lower end of the lever j carries a bowl or roll which enters a cam groove in the boss is fast on the main driving shaft b, whose rotation imparts a constant oscillating motion to the said lever and through same reciprocates the rod-or shaft j which in turn imparts an oscillating motion to the levers or arms 7i opposite each drum on both sides of the machine, these again giving a lateral to and-fro motion to the bobbin holders e which slide upon the spindle or shaft d.

In commencing to wind the yarn upon the tubes 9 the bowls e on the holders e occupy their highest ositions at the upper ends of the yokes h o the arms it, that is, at the farthest point from the fulcra h and, there fore, the said bobbin holders receive the the initial winding of the yarn upon the tubes. The lateral traverse given to the bobbin holders '6 increases the extent of traverse of the yarn on the tube or spool and, therefore, by reason of the roll e being at the farthest oint above or away from the fulcrum h the initial la er oLchase of yarn wound upon the tu e g is the longest end, as the front end of the holder 6 is gradually elevated by each successive layer wound upon the tube or spool, the rear end or point of connection between the frame and actuating lever de' scends and a proaches nearer and nearer to the fulcrum of said lever so that the mo tion imparted by the arm h to the bobbin holder adually diminishes and Winds each succeeding layer or chase of yarn in propertionately shortening or narrowing chases whereby the spool or bobbin is built u with a conical taper or nose at each end. hen the point of connection of the frame or holder e with the actuating lever arrives at the pivot center of said leven, the lateral traverse motion of the bobbin holder ceases and the subsequent layers or chases of yarn are Wound on uniformly from end to end, building up the remaining portion of the spool or cheese with the ends thereof parallel, as illustrated by the dotted line portions in Fig. 9. After passing the pivot center of the lever h, the

is wound on after the minimum traverse has been attained, the spool being then as shown in full line in Fig. 9, but, if required for warp, the yarn is built up uniformly from the shortest chase to the full size of cheese as indicated by dotted line in Fig. 9, the )OIlJlOIl represented in full line being adapte to be inserted in the shuttle as weft if the whole of the cheese is not used up as warp.

It has, as previously mentioned. hitherto been customary in this class of machine to guide the yarn or thread to the spool. or bobbin by passing it through the cam slot or. of the drum a, the revolution of said drum causing the yarn or thread to be traversed from end to end of the spool or bobbin and cross wound thereon. In order to avoid the disadvantages arising from this method of guiding the yarn or thread to the bobbin, we employ a separate guide for the purpose, independent of the drum but actuated by means of the cam slot wherein to give the necessary traverse motion.

We will now describe our improvements as combined with the type of machine hereinbefore referred to for winding warp or weft, or partly one and partly the other.

n is a bar occupying a convenient position in front of the drum a and supported in brackets 0 bolted to the pedestal c, the bar it being provided with rounded or beaded longitudinal edges it; There is a separate bar it for each Winding drum on and on each bar is mounted, so as to slide freely and easily thereon, a loose guide iece 1) having its upper face grooved longitu inally as at p to form a channel or way for the yarn or thread to travel through. The front end of the guide 1) is preferably extended upward for a short distance and is provided with a flared mouth or opening 7). leading to the channel or Way pto facilitate the insertion of the yard or thread ,in the guide. A pin p is formed on or secured to'the under-side of the guide piece p and is adapted to enter the cam groove a in the drum a.

Surrounding the bar 11, and interposed between either side of the guide piece p and the side brackets 0 at each end of the bar, are short springs 1* which admit of the full traverse of the guide piece p in either direction on the bar it and cushion it at each extremity of its motion. The pin or Stud 11 enters the cam slot q. and registers freely therein, and

. gages.

the action of the said cam slot as the drum rotates causes the guide piece p to be traversed first in one direction and then in the other longitudinally of the bar n, the yarn or thread being guided to the spool by the guide piece and also traversed thereby to cross wind it on the spool.

At the sides or edges of the cam slot a we secure strips or linings s of leather or the like to form noiseless surfaces against which the pin or projection 29' on the guide piece p env The edges of the linings s are preferably rounded or curved as shown at Fig. 5. The linings s are in this instance secured to the interior of the drum a by binding strips t of metal or other suitable mate rial secured to the inner faces of the drum by clips u soldered or brazed to the strips t and to the drum 0,. This method of securing the leather linings in position avoids the use of rivets or o'ther similar fastenings which are liable to project from the outer faces of the drum.

In the modification shown at Fig. 10, a length of wire '0 is substituted for the pin or stud p. This Wire 'U-iS bent at its upper end toform a guide eye '0 through which the yarn or thread is passed, and is bent at 0 around and soldered or brazed to the boss 12" of the guide piece p which in this instance is formed of a suitably shaped piece of thin sheet metal bent at one end around the slide bar n and having its delivery end turned up to form a fork p through which the yarn passes and is guided to the spool or bobbin.

The wire 1; passes down through the cam slot in the same manner as the pin. or stud p but, in this arrangement it is necessary to provide some means to hold the delivery end of the guide piece clear of the periphery of the drum a and the wire '1) is therefore carried down past the shaft 6, bent back upon itself and the end turned down to form a hook or yoke 0 fitting over and adapted to ride along the shaft 5 as the traversed to and fro on thecircular rod 12 by the action of the cam slot on the wire v.'

The advantage of our improvements will be appreciated by those skilled in the art.

The provision of a guide piece separate from and supported independently of the Winding drum and moved laterally across the width of the drum by the cam slot therein avoids the twisting and untwisting. of the guide piece is yarn, the lining of the sides of the cam slots with leather or. the like insuring a smooth, silent movement of the guide piece.

It will be understood that the details of construction of our improvements may be varied without departing from our invention.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is 1. The combination, with a driving shaft, and a split winding drum having its sections secured on the said shaft and forming a cam groove; of linings of soft material secured against the inside surface of the said drum and forming lateral projections at the edges of its said cam groove, a guide bar, and a guide for the yarn slidable on the said guide 'bar and provided with a projection which engages with the laterally projecting edges of the said linings.

2. The combination, with a driving shaft, and a split winding drum having its sections secured to the said shaft and forming a cam groove; of linings of soft material arranged inside thesaid drum and forming lateral projections at the edges of its said cam groove, binding strips bearing against the main portions of the said linings, clips secured to the said strips and the drum sections and holding the said linings in place, a guide bar, and a guide for the yarn slidable on the said guide bar and-provided with a projection which engages with the-laterally projecting edges of the said linings.

' 3. The combination, with a driving shaft,"

and a split winding drum having its sections secured to the said shaft and forming a cam groove; of linings of soft material secured to the drum sections and forming lateral proj-ections at the edges of its said cam groove, a guide bar, and a' guide for the yarn slidable on the said guide bar and provided with an arm which projects between the laterally projecting portions of the said linings and engages slidably with the said driving shaft.
